I brought my HDD to data recovery center and they have diagnosed and confirmed the issue to be of head problem.
So, the only option is to do data recovery, which is very costly and I don’t intend to pay that kind of money.
Therefore, my issue is officially closed now.
But before I close off, I would like to provide some knowledge which I’ve learnt during the painful weeks of troubleshooting it with the hope that it will help someone who have the same / similar problem as mine.
Of course, what I will listing below is not the complete solution as I’m still a novice, but at least it should be able to shed some light to the issue.
- Looks for signs / symptoms.
If yes, is the disc spinning?
If yes, are there any clicking sounds?
If yes, most probably it is head problem. Seek professional help to recover data.
Does it have light on?
If yes, is the light blinking?
Is it detected in My Computer?
Most of the time, it is a no but if it is detected in My Computer but the files are gone or not accessible, then it could be some other issues which are not within the scope of this troubleshooting.
Is it detected in Disk Management?
If detected, try to assign drive letter.
Is it detected in Device Manager?
If detected, try to update firmware.
- Basic troubleshooting.
Try different USB cable?
If it is on USB 3.0, try cable with USB 2.0.
Try different USB port?
If using desktop, connect to the USB port at the rear instead of the front.

Try different power adapter? (make sure it has the same voltage as original power adapter)
Try connect the power adapter direct to the wall power socket instead of power extension / hub.
Try different laptop / desktop?
Try different OS?
- Advanced troubleshooting. (Attention: Requires removing the HDD from the casing which will void the warranty!)
Connect the HDD (without the bridge board attached) to computer by via USB-to-SATA cable.
If detected in Device Manager, check if it display the correct HDD model.
Sometimes it detected the bridge board in the USB-to-SATA cable instead of the HDD.
If not detected, it could be PCB or internal HDD issue.
Connect the HDD (without the bridge board attached) to motherboard by via SATA port.
If detected, the HDD is fine. Otherwise, it could be PCB or internal HDD issue.
To fix the PCB, you will have to find the exact model number and do a swap.
In addition, need to do a ROM transfer as well (requires soldering).
There are many sources (and youtube video) which discuss about PCB replacement.
Besides replacing the PCB, there have been cases whereby PCB issues are caused by oxidisation.
Refer to http://malthus.zapto.org/viewtopic.php?f=86&t=649&p=3971&hilit=oxidisation#p3971 (thanks to fzabkar for sharing)
Connect the bridge board (without the HDD) to laptop by using the original cables.
If detected, the bridge board is fine. Otherwise, it is faulty.
I’m not sure how to fix the bridge board though.
Attach clear photo of the PCB board.
Attach clear photo of the bridge board (control board).
Attach clear recording of the HDD sounds when powering up.
Hope this helps!
